ABSTRACT

A user interface and associated methods for machine aided authoring and translation is provided. The user interface can display strings and associated metadata to assist with authoring and translations. The metadata can be used to mark the strings. The metadata can include one or more constraints which correspond to evaluation criteria and one or more anchor points operable to project the constraints against a string.

BACKGROUND

Generally described, localizing resources for computer systems duringsoftware development involves transforming source data corresponding toone market into target data corresponding to a different market. Forexample, localization can involve translating source data in onelanguage into target data in another language. Localization can alsoinvolve transforming data between markets in the same language, such astransforming source data corresponding to Japanese for children intotarget data corresponding to Japanese for adults. A resource isgenerally defined as an item of data or code that can be used by morethan one program or in more than one place in a program, such as adialog box. One example of a resource is an error message string used toalert a computer user of an error condition. Additionally, the errormessage can contain one or more placeholders to be replaced with thevalue of the placeholder before the message is displayed.

Various assumptions can be associated with a resource. For example, theauthor of an error message such as “File <PH> not found”, where “<PH>”is an example of a placeholder to be replaced with the name of a file,may assume that the file name will be provided at a later time and thatthe reader of the message understands the meaning of the term “file.” Touse the error message in various markets, it may need to be translatedinto several languages. In a typical development environment, aword-for-word translation may be used to localize a resource. However,the resulting translation may not capture contextual data associatedwith the resource. For example, a word in a resource, such as the word“file”, can have more than one meaning and thus the context in which theword is used is needed to generate a correct translation. Additionally,functional items, such as placeholders, need to provide functionality intarget data that corresponds to the functionality provided in sourcedata. For example, the “<PH>” in the example error message needs tofunction such that it is replaced with the name of a file in anytransformation of the error message.

One approach to capturing contextual and functional information duringlocalization involves comparing each individual assumption associatedwith the source resource against the target resource to ensure that thetarget resource complies with every assumption. For example, oneassumption associated with a source resource can be that invalidcharacters are ‘*’ and ‘\’. An additional assumption associated with thesame resource can be that invalid characters are ‘%’ and ‘\’. Tovalidate the target resource using these assumptions, a validationengine could first check that the target string does not contain either‘*’ or ‘\’. Next, the validation engine could check that the targetstring does not contain ‘%’ and ‘\’. However, checking each individualassumption is not efficient. Further, individual assumptions may beincompatible with other individual assumptions or may be redundant.

Pseudo-localization of a resource can be used to ensure that assumptionsare correctly captured so that they can be preserved in a target. Theprocess of pseudo-localization typically involves generating a randompseudo-translation of a source string. The pseudo-translation can thenbe tested, in a process generally known as validation, to ensure thatassumptions from the source string are preserved in thepseudo-translation. However, typical tools that performpseudo-localization of a source string for testing purposes do not usethe same validation techniques as tools used to validate targettranslations. Thus, localized software is not tested as thoroughly aswould be possible if pseudo-localized resources were able to bevalidated in the same manner.

DETAILED DESCRIPTION

Generally described, the present invention is directed toward systemsand methods for processing and validating formatted data. Morespecifically, in accordance with the present invention, source data iscompiled into metadata including one or more constraints and one or morecorresponding anchor points. The one or more constraints correspond toevaluation criteria which can be used to validate a localized version ofa string. Various processing components can consume the compiledmetadata. For example, metadata can be projected onto a string, used tovalidate a string, used to assist in translation of a string, used tocorrect a string, and used to display a marked string. Although thepresent invention will be described with relation to illustrative userinterfaces and operating environments, one skilled in the relevant artwill appreciate that the disclosed embodiments are illustrative innature and should not be construed as limiting.

With reference now to FIG. 1, an illustrative operating environment 100includes a metadata compiler 104 and a metadata optimizer and arbitrator106 operable to generate normalized metadata for consumption by variousprocessing and translation components. The metadata compiler 104 isoperable to compile source data 102 into metadata. In an illustrativeembodiment, source data 102 can include a source string. For example,source data 102 can include the following string: “This is a string.”Further, source data 102 can include a rule. For example, the sourcedata 102 could include the following rule: “{MaxLen=25}”. Rules will bedescribed in greater detail below. Source data 102 can further includeresource information. Resource information can be used to specifyattributes of a resource, such as the corresponding platform, thecorresponding usage of the resource and the corresponding language ofthe resource. For example, resource information can be used to specify aparticular platform that corresponds to a source or target string.Additionally, the metadata compiler 104 can infer restrictions byanalyzing source data 102. For example, a compiler component 104 caninfer a placeholder by parsing a source string. Alternatively, aplaceholder in a source string can be inferred based on correspondingresource information.

In an illustrative embodiment, compiled metadata generated by a metadatacompiler 104 can include one or more constraints which correspond toevaluation criteria and one or more anchor points for mapping the one ormore constraints to a string. The metadata optimizer and arbitrator 106obtains compiled metadata and generates normalized metadata using thecompiled metadata. The normalization process will be discussed in moredetail below. In an illustrative embodiment, both the compiled metadataand the normalized metadata can correspond to abstract metadata.Abstract metadata corresponds to metadata that has not yet been placedagainst a string. Once metadata has been compiled and normalized, themetadata can be used by one or more processing components in theoperating environment 100. The processing components generally consumethe metadata and can perform additional tasks. A first set of processingcomponents 108, 110, 112, and 114 can be used to manipulate a stringand/or corresponding metadata while a second set of processingcomponents 116, 118, 120, and 122 can be used to translate a string.

Within the first set of processing components, a projection component110 can utilize the metadata to project the one or more constraints ontoa string according to the corresponding anchor points. Additionally, avalidation component 108 can utilize metadata to validate a stringagainst the one or more constraints included in the metadata. Validatinga string involves evaluating the criteria associated with theconstraints that correspond to the string. If the criteria correspondingto a constraint are satisfied, then the constraint evaluates to “true”.Conversely, if the criteria corresponding to a constraint are notsatisfied, then the constraint evaluates to “false”. In an alternativeembodiment, constraints evaluate to a severity level. For example,constraints may evaluate to a warning or an error. A correctioncomponent 112 can utilize metadata to modify a string such that thecorresponding constraints included in the metadata are satisfied.Additionally, a display component 114 can display a string that has beenmarked according to corresponding metadata.

The illustrative operating environment 100 can also include a pluralityof processing components operable to translate a string based on thecompiled metadata. In an illustrative embodiment, the translationcomponents can translate all or portions of a string as dictated by themetadata. Alternatively, a translation component can generate asuggested translation which violates one or more of the constraintsincluded in the metadata. In such a case, portions of the suggestedtranslation which violate the constraints can be marked. Markingsuggested translations in this manner can signal to a user the portionsof the suggested translation which need to be modified for theconstraints to be satisfied. Marking will be discussed in more detailbelow. For example, the metadata can include one or more constraintsthat lock one or more portions of the string and that prevent thoseportions from being translated. In another example, the metadata caninclude a set of constraints that prevents a corresponding placeholderin a string from being translated. A translation component can alsoretrieve translations from a data store and cause the translations to bemarked according to corresponding metadata. With continued reference toFIG. 1, the operating environment 100 can include an auto-translationcomponent 116 operable to translate a string in accordance withcorresponding metadata. As will be appreciated by one skilled in theart, auto-translation involves matching a string with a database ofstrings that includes corresponding translations. Further, the operatingenvironment 100 can include a machine-translation component 118 that cantranslate a string in accordance with corresponding metadata. As will beappreciated by one skilled in the art, machine translation involves theuse of computer hardware or software to translate text from one languageinto another. Still further, the operating environment 100 can include amanual translation component 120 that can translate a string inaccordance with corresponding metadata. As will be appreciated by oneskilled in the art, manual translation typically involves the use of ahuman to translate from one language into another. Even further, theoperating environment 100 can include a pseudo-localization component122 that can be used to provide a pseudo-translation of the string to beused for testing purposes. Pseudo-localization will be described ingreater detail below. Although the illustrative operating environment100 is illustrated with all of the above processing components, oneskilled in the relevant art will appreciate that the operatingenvironment 100 can vary the number of processing components. In anillustrative embodiment, metadata can be consumed in a manner that isagnostic to workflow.

In an illustrative embodiment, compiled metadata can be utilized topreserve the intent, context, and format of a communication whileallowing for actual data in the transaction to be converted asappropriate to a corresponding market or locale. For example, metadatacan be utilized to preserve the assumptions associated with a sourcestring after the string has been translated. In one aspect, theconstraints generated by a compiler 104 are declarative and thusdescribe what the corresponding restriction or assumption is, but doesnot describe how to fulfill it. Because the constraints are declarative,consumption of the constraints is more flexible. In an illustrativeembodiment, constraints can be combined through anchoring to build more“complex” constraints.

In another aspect, constraints are categorized. In an illustrativeembodiment, constraints can be categorized according to a severitylevel. For example, a constraint that is not satisfied can issue anerror or a warning. In another embodiment, a constraint can becategorized according to whether the constraint operates on code pointsor characters. For example, functional constraints can operate on codepoints whereas terminology constraints can operate on characters.Specifically, a string representing the term “file” may be associatedwith a hotkey such that on a functional level the string appears as“fil&e”. A terminology constraint can operate on the characters in thestring “file” and would thus not see the “&” while a functionalconstraint can operate on code points and would be able to detect the“&”. Furthermore, a constraint can be categorized according to whetherit is positive or negative. For example, a positive constraint canspecify how a corresponding portion of a string should appear whereas anegative constraint can specify how a corresponding portion of a stringshould not appear. Still further, a constraint can be categorizedaccording to whether the constraint checks counts, elements, orsequences. For example, a count constraint can limit the length of astring or substring. A constraint that checks elements can validatebased on the value of the corresponding elements. Elements cancorrespond to characters or code points. Additionally, constraints canbe case-sensitive or case-insensitive. Likewise, constraints can beculture-sensitive or culture-insensitive. Constraints can also beregular expressions. A constraint that checks sequences can validatebased on the value of the corresponding sequence, such as a substring.In a further aspect, constraints are instance agnostic. For example, aconstraint on a string corresponding to the English language willvalidate in the same manner as a constraint on a string corresponding tothe Spanish language. Alternatively, constraints can belanguage-specific. In a further aspect, constraints can be projectedonto a string instance. Dependencies can also exist between constraints,such that, for example, the result of the evaluation of one constraintwould correspond with the result of the evaluation of anotherconstraint.

With reference now to FIG. 2, the illustrative operating environment 100of FIG. 1 can include a plurality of metadata compilers 104 operable tocompile source data into metadata. In an illustrative embodiment, theplurality of metadata compilers 104 operate in parallel, such thatsource data 102 from several sources can be compiled into metadata. Themetadata compilers 104 may also operate in series such that eachcompiler 104 performs a different compilation function. Further, in anillustrative embodiment, several different metadata compiler 104versions may be operable in the illustrative operating environment 100.For example, a user responsible for entering source data may growaccustomed to the interface corresponding to a version 1.0 metadatacompiler. That user can continue to use the version 1.0 compiler even asa version 2.0 compiler comes on line for use by others. As illustratedin FIG. 2, the metadata optimizer and arbitrator 106 can obtain compiledmetadata from each of the metadata compilers 104 and normalize themetadata. Normalization can involve consolidating redundant constraintsand resolving incompatibilities amongst constraints such that theprocessing components 108, 110, 112, 114, 116, 118, 120, and 122 receivea consistent set of metadata. The normalization process will bediscussed in more detail below.

With reference now to FIG. 3, the interaction by various components ofthe operating environment 100 to process and validate metadata will bedescribed. In an illustrative embodiment, an authoring user interface302 can obtain user input for compilation by one or more metadatacompilers 104. The user input can correspond to source data 102 and caninclude one or more processing attributes. As discussed above, the oneor more metadata compilers 104 obtains the user input as source data andcompiles the user input into metadata. User input can be directed to anyone or more of the metadata compilers 104. For example, a metadatacompiler 104 can accept specific types of source data 102, such assource data that includes only a source string or source data thatincludes a source string and a rule. Further, by examining user input, ametadata compiler 104 can infer additional constraints.

Still with reference to FIG. 3, in an illustrative embodiment, themetadata optimizer and arbitrator 106 obtains abstract metadata andgenerates normalized abstract metadata. As will be described in greaterdetail below, the metadata optimizer and arbitrator 106 filters themetadata from the one or more compilers 104 to remove redundantconstraints and/or incompatible constraints. A projection component 110obtains abstract metadata and projects the metadata onto a targetstring. As discussed above, in an illustrative embodiment, the metadataincludes one or more constraints which correspond to evaluation criteriaand one or more anchor points mappable to a target string. Projectingmetadata involves placing the one or more constraints on top of a targetstring according to the corresponding anchor points. For purposes ofverification, the target string can be the source string.

A validation component 108 obtains projected metadata and validates thestring against the one or more constraints. In an alternativeembodiment, the validation component 108 can validate a string againstabstract metadata. Validating a string against metadata involvesdetermining whether the string satisfies the evaluation criteriacorresponding to the constraints included in the metadata. In anillustrative embodiment, a string fails to validate if any correspondingevaluation criterion is not satisfied. In an alternative embodiment astring fails to yalidate if any corresponding evaluation criterion isnot satisfied and results in the generation of an error. For example,some failed evaluation criteria can result in the generation of awarning, which may not prevent the string from validating. An authoringuser interface 302 can obtain results of the validation process from thevalidation component 108 and display the validated string to a user. Inan illustrative embodiment, the string is marked according to thecorresponding constraints. For example, the string can be marked to showthe user which portions of the string satisfy the constraints and whichportions fail to satisfy the constraints. Further, the string can bemarked to alert the user of the location of errors. For example, syntaxerrors in the source string can be marked. In an illustrativeembodiment, the string may be auto-corrected so that it satisfies thecorresponding constraints. In an alternative embodiment, suggestedmodifications may be displayed to a user for selection. The process ofmarking and displaying a string will be discussed in more detail below.

With reference now to FIG. 4, the interaction of various components ofthe operating environment 100 to localize a string will be described. Inan illustrative embodiment, an authoring user interface 302 can obtainuser input for compilation by one or more metadata compilers 104. Ametadata optimizer and arbitrator 106 obtains abstract metadata from theone or more metadata compilers 104 and generates normalized, abstractmetadata as described above. A projection component 110 obtains abstractmetadata and user input including a target string from a translationuser interface 402 and projects the metadata onto the target string. Inan illustrative embodiment, the target string is a string a user desiresto validate and translate. A validation component 108 validates thetarget string against the projected metadata. In an alternativeembodiment, the validation component 108 can obtain abstract metadataand a target string and validate the target string using the abstractmetadata. Further, the validation component 108 can examine a sourcestring and a corresponding target string and check that the same set ofguarantees are present on both strings.

Translation component 404 obtains the results of the validation processand translates the validated target string. A correction component 112can obtain translated results and can modify the translation such thatit satisfies the associated metadata. Further, a translation userinterface 402 can obtain the corrected results and display the correctedtranslation to a user. The translation user interface 402 can display astring using associated metadata to mark portions of the string. Markinga string for display to a user will be discussed in more detail below.

In an illustrative embodiment, the translation user interface 402 canobtain validation results from a validation component 108. Further, thetranslation user interface 402 can display a marked string so that auser can modify the string such that the string satisfies the associatedconstraints. Still further, suggested, selectable modifications can bepresented to a user so that a user may choose which modifications toapply. For example, suggested, selectable modifications can be presentedas auto-completes. In an illustrative embodiment, the translation userinterface 402 can obtain translated results from the translationcomponent 404. Further, the translation user interface 402 can displaythe translated string to the user with markings that correspond to theassociated metadata. A user can modify the translated string such thatit satisfies the associated constraints. In an illustrative embodiment,translation component 404 can correspond to an auto-translationcomponent 116, a machine translation component 118, or a manualtranslation component 120. Further, translation component 404 canutilize pseudo-localization techniques to provide a pseudo-localizedstring. Pseudo-localization techniques will be discussed in more detailbelow. In an illustrative embodiment, the components of the system canbe distributed. For example, user interfaces 302 and 402 can exist onclient machines while the one or more compiler components 104 exit on aserver. Alternatively, the user interfaces 302 and 402 and one or morecompiler components 104 can exist on the same machine.

With reference now to FIG. 5A, in an illustrative embodiment 500,metadata includes one or more constraints 502, 504, 506, 508, 510, 512,and 514 which correspond to evaluation criteria. The constraints caninclude one or more anchor points 520, 518, 516, and 522 which can beused to project the one or more constraints 502, 504, 506, 508, 510,512, and 514 on top of a string 524. In an illustrative example, string524 can correspond to a filename such as “CALCULATOR.EXE.” Constraints1.1 and 1.2 (502 and 504) can be used to evaluate the portion of thestring 524 between anchor points 520 and 522. Constraints 2.1, 2.2 and2.3 (506, 508, and 510) can be used to evaluate the portion of thestring 524 located between anchor points 520 and 518. Constraints 3.1and 3.2 (512 and 514) can be used to evaluate the portion of the string524 located between anchor points 516 and 522.

In an illustrative embodiment, multiple constraints can be placedbetween anchor points. Additionally, constraints are combinable thusallowing for an initial small set of constraints to represent a largenumber of concepts or assumptions. For example, there are several rulesthat can be used to lock a portion of a string while a single constraintcan be used to implement the lock. Thus each of the rules when compiledwould use the single lock constraint to implement the lock. Stillfurther, the illustrative metadata can be used to process stringsencoded in any character set, such as the ASCII character set or theUnicode character set.

The one or more anchor points 520, 518, 516, and 522 can be placedbefore or after elements in the string 524. For example, anchor point520 is placed before element “C” 501. Similarly, anchor point 518 isplaced after element “R” 503 and before element “.” 505 while anchorpoint 516 is placed after element “.” 505 and before element “E” 507.Likewise, anchor point 522 is placed after element “E” 509. In anillustrative embodiment, elements in a string correspond to characters,such as Unicode characters. Alternatively, elements in a string cancorrespond to code points, such as Unicode code points.

In an illustrative embodiment, an anchor point can be loosely anchoredor hard-anchored to a point before or after any of the elements in thestring. An anchor point that is hard-anchored to a point on a string isfixed to that point. Conversely, an anchor point that is looselyanchored can move within a range of points on the string. For example, aconstraint can be anchored to a beginning anchor point and an endinganchor point. A constraint anchored to a loose beginning anchor pointand a loose ending anchor point evaluates to “true” if the correspondingevaluation criteria can be satisfied by any sequence found between thetwo anchor points. Conversely, a constraint anchored to a hard beginninganchor point and a hard ending anchor point evaluates to “true” if thecorresponding evaluation criteria can be satisfied by the sequence thatstarts at the beginning anchor point and ends at the ending anchorpoint. Further, a constraint that is not anchored evaluates to “true” ifany sequence within the string 524 satisfies the constraint. Stillfurther, constraints can be anchored in one manner to one anchor pointand anchored in another manner to another anchor point. In regards toterminology within the present application, describing a constraint ashard-anchored to an anchor point is equivalent to describing theconstraint as anchored to a hard anchor point. Similarly, describing aconstraint as loosely-anchored to an anchor point is equivalent todescribing the constraint as anchored to a loose anchor point. Examplesof various types of anchoring will be provided below.

In an illustrative embodiment, the one or more constraints 502, 504,506, 508, 510, 512, and 514 can be projected onto a string 524 atruntime. Further, the one or more constraints 502, 504, 506, 508, 510,512, and 514 can be evaluated at runtime. Compiling the one or moreconstraints 502, 504, 506, 508, 510, 512, and 514 and one or more anchorpoints 520, 518, 516, and 522 from source data is more computationallyintensive than projecting and validating the constraints. Therefore,allowing projection and validation of constraints against a string atruntime without requiring re-compilation provides for more efficientprocessing of strings. In an illustrative embodiment, the one or moreconstraints 502, 504, 506, 508, 510, 512, and 514 cannot be projectedonto a string in a manner that would validate the string if the stringis in fact invalid.

With reference now to FIG. 5B, in an illustrative embodiment 550,constraints 552, 556, 558, 560, and 562 can be used to validate string525. For example, string 525 can be representative of a filename in acomputer system that must conform to the specified constraints 552, 556,558, 560, and 562 to be valid. Before validating string 525, constraints552, 556, 558, 560, and 562 can be placed on top of the string 525 usinganchor points 516, 518, 520, and 522. For example, projection component110 can place constraints 552, 556, 558, 560, and 562 onto string 525according to anchor points 516, 518, 520, and 522. In an illustrativeembodiment, the constraints 552, 556, 558, 560, and 562 can be projectedonto the string using the following procedure:

-   -   (1) Identify the beginning of the string as anchor point 520.    -   (2) Identify the end of the string as, anchor point 522.    -   (3) Add constraint 552 that requires the string to contain the        sequence of elements “.” (dot).    -   (4) Identify the beginning of the dot as anchor point 518.    -   (5) Identify the end of the dot as anchor point 516.    -   (6) Add constraint 556 anchored to anchor points 520 and 518        that requires the substring to have at most 8 elements.    -   (7) Add constraint 556 anchored to anchor points 520 and 518        that requires the substring to have at least 1 element.    -   (8) Add constraint 560 anchored to anchor points 520 and 518        that contains the list of invalid elements for a file name        (asterisk, dot, space, etc.).    -   (9) Add constraint 562 anchored to anchor points 516 and 522        that requires the substring to be the sequence of elements “exe”        (case insensitive).

In this manner, a simple, small set of constraints can be used to build“complex” constraints. In an illustrative embodiment, a user may buildthe “complex” filename constraint described above by entering a rulecorresponding to each constraint into an authoring user interface 302and running the constraints through the illustrative operatingenvironment 100 depicted in FIG. 3. In another embodiment, a user cansimply enter a string into the authoring user interface 302 which theone or more metadata compilers 104 interprets as a filename and uses togenerate the set of constraints depicted in FIG. 5B. In a furtherembodiment, a user can enter a source string representative of afilename and a set of attributes which instruct the one or more metadatacompilers 104 to generate the set of constraints which correspond to afilename. In a further embodiment, a user can enter a source stringrepresentative of a filename and a rule, such as {FILENAME}, whichcompiles into constraints 552, 556, 558, 560, and 562.

The exemplary constraints 552, 556, 558, 560, and 562 depicted in FIG.5B can be used to validate the string 525. For example, validationcomponent 108 can utilized constraints 552, 556, 558, 560, and 562 tovalidate string 525. As described above, projected constraints 552, 556,558, 560, and 562 can be hard-anchored, loosely anchored, or notanchored to the string 525. In an illustrative embodiment, the type ofanchoring used to place a constraint is determined by the correspondingevaluation criteria. Constraint 552 is an example of a constraint thatmay not be anchored to string 525. A constraint that is not anchored tostring 525 must be separated from anchor point 520 on its left side by aminimum of 0 characters towards the end and must be separated fromanchor point 522 on its right by a minimum of 0 characters towards thebeginning. Thus, a constraint that is not anchored evaluates to “true”if some portion of string 525 satisfies the constraint. In theillustrative example, constraint 552 evaluates to “true” because theportion of the string between anchor points 518 and 516 satisfies theconstraint.

A constraint that is not anchored is equivalent to a constraint that isloosely anchored to the beginning of string 525 and loosely anchored tothe end of string 525. A constraint that is loosely anchored allowselements to exist or be inserted between the portion of the string thatsatisfies the constraint and its anchor point. For example, a constraintthat requires the sequence “CUL” to be contained between anchor points520 and 518 can be loosely anchored to anchor point 520 and looselyanchored to anchor point 518. The loose anchoring on each end of thisexemplary constraint allows string 525 to satisfy this constraint eventhough the sequence “CAL” exists between the beginning of the constraintand anchor point 520 and sequence “AT” exists between the end of theconstraint and anchor point 518.

In an illustrative embodiment, constraint 556 is an example of aconstraint that is hard-anchored to anchor point 520 and hard-anchoredto anchor point 518. Hard-anchoring a constraint to an anchor pointforbids elements from appearing between the anchor point and theconstraint. Constraint 556 is satisfied when eight or fewer elements arecontained between anchor points 520 and 518. Because the sequencecontained between anchor points 520 and 518 contains exactly 8characters, the constraint is satisfied. If the constraint were nothard-anchored to anchor points 520 and 518, then additional elementscould exist between the anchor points and the constraint and thus theconstraint could be satisfied in situations in which the sequencebetween anchor points 520 and 518 contained more than eight elements.Constraint 558 is an example of a constraint that can be hard-anchoredto anchor point 520 and that can be hard-anchored to anchor point 518.Constraint 558 is satisfied when one or more items are contained betweenanchor points 520 and 518. Because the sequence contained between anchorpoints 520 and 518 contains eight items, and one ≦ eight, the constraint558 is satisfied. In an alternative embodiment, constraint 558 can behard-anchored to anchor point 520 and loosely anchored to anchor point518.

With continued reference to FIG. 5B, constraint 560 is hard-anchored toanchor point 520 and hard-anchored to anchor point 518. Constraint 560evaluates to “true” if each element in the sequence between anchorpoints 520 and 518 does not equal an asterisk, a period, or a space.Because none of the restricted items appear in the sequence betweenanchor points 520 and 518, the constraint evaluates to “true.”Constraint 562 is hard-anchored to anchor point 516 and hard-anchored toanchor point 522. Further, constraint 562 evaluates to “true” if thesequence between anchor points 516 and 522 is equal to the sequence“EXE” (case insensitive). Because the sequence between anchor points 516and 522 equals “EXE”, constraint 562 evaluates to “true.” Although notdepicted in FIG. 5B, a constraint that required string 525 to end withthe sequence “.EXE” would be hard-anchored to anchor point 522 andeither not anchored at the beginning or loosely anchored to anchor point520. Conversely, a constraint that required string 525 to begin with thesequence “CAL” would be hard-anchored to anchor point 520 and either notanchored at the end or loosely anchored to anchor point 522.

In an illustrative embodiment, multiple types of anchor points can existat the same point on a string. For example anchor point 522 cancorrespond to a loose anchor point and a hard anchor point. In anillustrative embodiment, constraint 552 could be loosely anchored toanchor point 522 whereas constraint 562 could be hard-anchored to anchorpoint 522.

In an illustrative embodiment, FIG. 5B depicts how string 524 from FIG.5A could be modified such that it satisfies exemplary constraints 552,556, 558, 560, and 562. For example, string 524 can be modified bycorrection component 112 such that constraints 552, 556, 558, 560, and562 are satisfied. String 524 can be modified in an authoring userinterface 302 or a translation user interface 402 according to markingson the string. Further, string 525 (“CALCULAT.EXE”) can be the result ofa user entering string 524 (“CALCULATOR.EXE”) into a translation userinterface 402 and validating and correcting string 524 againstconstraints 552, 556, 558, 560, and 562. Constraints can be configuredsuch that they are case-sensitive or case-insensitive. For example,constraint 562 can be configured such that it is case sensitive and willonly match against the sequence “EXE”. Alternatively, constraint 562could be configured such that it is case insensitive and will matchagainst any combination of uppercase and lowercase characters whichcombine to spell “exe”.

With reference now to FIG. 5C, constraints 552, 556, 558, 560, and 562can be used in an attempt to validate string 524. In an illustrativeembodiment, a user can enter string 524 into a translation userinterface 402 and attempt to determine whether the string 524 is a validfilename using constraints 552, 556, 558, 560, and 562. Althoughconstraints 552, 558, 560, and 562 evaluate to “true”, constraint 556evaluates to “false”, and thus string 524 would not be valid. In anillustrative embodiment, it is not possible to place a set ofconstraints against a string in a manner that validates an invalidstring. Thus, users can direct the placing of constraints against astring to be validated. This allows for compilation to take place priorto runtime while placing and validating can be performed at runtime. Ina typical environment, compilation is significantly more computationallyexpensive than placing and validation, and thus significant efficienciescan be realized by performing compilation prior to runtime.

With reference now to FIG. 5D, several constraints 596, 590, 586, 574,576, 578, and 584 can be projected onto an exemplary string 572 andassist in processing the string 572. In an illustrative embodiment,constraint 596 limits the portion of the string 572 before the firstcolon 594 to a maximum of 255 elements. In a similar manner, constraint590 limits the portion of the string 572 after the third colon 592 andbefore the fourth colon 582 to a maximum of 10 elements. Similarly,constraint 586 limits the portion of the string 572 after the fourthcolon 582 to a maximum of 35 elements. Because each substring containsless than the maximum number of constraints specified by the associatedconstraints, each of the maximum-length constraints 596, 590, and 586 issatisfied. Constraints 574, 578, and 584 forbid any of the elements inthe respective, associated substrings from containing a “:” (colon).Because none of the substrings contain colons, constraints 574, 578, and584 are satisfied. Constraints 576 and 588 are lock constraints thatprevent the corresponding sequence from being localized. Thus, lock 576prevents the substring “:12:03:” from being localized while lock 588prevents the fourth colon 582 from being localized.

Although FIGS. 5A-5D depict strings in English, which is written fromleft to right, it will be appreciated that the present invention canprocess and translate resources in any language. For example, thepresent invention is aware of right-to-left languages, such as Arabicand Hebrew, and works appropriately with them.: In an illustrativeembodiment, the present invention conducts operations on the internalrepresentation of a string in memory, as opposed to the display view, inorder to deal appropriately with strings in any language.

In an illustrative embodiment, rules can be used to generate metadata.For example, a user can input a rule, in addition to a source string,using the authoring user interface 302. In an illustrative embodiment, arule can be compiled into metadata including one or more constraintswhich correspond to evaluation criteria and one or more correspondinganchor points. Further, the metadata can be used to validate a string.Several different types of rules can be used to generate constraints.For example, the rule set (or instruction set) can include rules thatcorrespond to fixed placeholders, numbered placeholders, escapedcharacters, escaped placeholder characters, invalid characters, validcharacters, restrictions relating to sequences that can be used to beginor end a string, and restrictions related to sequences that must appearin the string. Further, the rule set can include a split rule and asubstring rule.

In an illustrative embodiment, a placeholder can have special meaningand is analogous to a variable that needs to be replaced by its valuebefore it is displayed. Placeholders are typically not translated by atranslation component 404. For example, a set of constraints can beoperable to prevent a corresponding placeholder from being translated.In an illustrative embodiment, fixed placeholders correspond to aspecific type. For example, a fixed placeholder can be represented by asequence, such as ‘% s’ or ‘% d’. Further, before a fixed placeholder isdisplayed it can be replaced with a value of the type specified by thefixed placeholder. For example, a fixed placeholder of the type ‘% s’can be replaced with a string whereas a fixed placeholder of the type ‘%d’ can be replaced with an integer. In an illustrative embodiment, afixed placeholder in a source string cannot be switched with anotherplaceholder in the source string. Further, fixed placeholders appear ina translation in the same order as they appear in a source string.Because the ordering of fixed placeholders is preserved in atranslation, the number of occurrences of fixed placeholders isimplicitly preserved.

In an illustrative embodiment, a numbered placeholder corresponds to anindex. Further, numbered placeholders can be swapped and repeated in asource string. Still further, numbered placeholders can exist in atranslation in any order. For example, numbered placeholder ‘{0}’ mayappear before numbered placeholder ‘{1}’ in a source string, but canappear after numbered placeholder ‘{1}’ in a translation. In anillustrative embodiment, fixed placeholders and numbered placeholderscan be inserted into a string by a user wherever the correspondingplaceholders should appear. However, in practice, a target string is notvalid if the count of fixed placeholders in the target string differsfrom the count of fixed placeholders in a corresponding source string.

In an illustrative embodiment, a rule can indicate character orcharacter sequences to be escaped. For example, the character ‘\’ canhave special meaning within a string and should thus be escaped, such asby preceding the character with another ‘\’. In an illustrativeembodiment, the syntax to create an escaped character constraint is ofthe form {EscapeChars, ‘x=yy’}, where ‘x’ is a sequence of charactersthat cannot exist in the string and ‘yy’ is a sequence of charactersthat should be used instead of ‘x’. Further, in an illustrativeembodiment, if ‘yy’ is empty, then the corresponding ‘x’ parametercannot exist in the string. A similar rule can indicate character orcharacter sequences to be escaped within a string or substring, exceptfor within the regions covered by a specific set of constraints, such asthe set of constraints defined by a placeholder. This rule can prevent auser from accidentally adding a placeholder in a string.

In an illustrative embodiment, a rule can correspond to a constraintwhich forces a string or substring to only contain a set of characters.The characters can be defined as a regular expression span, a set ofcharacters, or a codepage. Conversely, a rule can correspond to aconstraint which forces a string or substring to not contain a set ofcharacters. For example, constraint 560 of FIG. 5B can be generated bysuch a rule. Rules can also correspond to constraints which verify thata string begins, contains, or ends with a specified value. For example,in an illustrative embodiment, constraints 552 and 562 of FIG. 5B can becompiled from rules that correspond to constraints to verify whether astring contains or ends with a specified sequence of characters,respectively.

In another illustrative embodiment, a split rule can also be used todivide a string into substrings according to specified parameters. Thesplit rule protects the section of a string covered by the parametersand requires those sections to exist in a corresponding translation.Further, sections of a string not covered by the parameters can be usedas substrings. Even further, the substrings found can be used assubstring parameters in other rules. Other rules can be dependent on thesplit rule, and thus the split rule can be processed before any rulethat can use the substring parameters.

In another illustrative embodiment, a substring rule can also be used todivide a string into substrings according to specified parameters. Thesubstring rule protects the section of a string not covered by theparameters and requires those sections to exist in a correspondingtranslation. Further, sections of a string covered by the parameters canbe used as substrings. In a manner similar to the split rule, thesubstrings found can be used as substring parameters in other rules.Other rules may be dependent on the substring rule, and thus thesubstring rule would be processed before any rule that can use thesubstring parameters.

In an illustrative embodiment, substring and positional parameters canbe used with the rules to generate constraints with corresponding anchorpoints. Positional parameters essentially expose the anchor points in astring to a user. Further, a user can specify whether a parameter iscase-sensitive, case-insensitive or a regular expression. Still further,multiple types of parameters can be combined within a rule. Evenfurther, culture parameters can be represented by numeric values orstring values.

In an illustrative embodiment, positional parameters can be used tospecify portions of a string to which a constraint applies. Positionalparameters can use the following syntax: (s+|e−) x . . . (s+|e−) y. Inthe exemplary syntax, ‘x’ specifies the beginning position and ‘y’specifies the ending position within a string. Further, ‘s+’ and ‘e−’are optional modifiers which specify that the position is from the startor from the end of a string and that the position is anchored to thatlocation. Parameters can operate on virtual separators betweencharacters in a string. For example, parameter ‘s+0’ indicates theposition prior to the first character in a string. Conversely, parameter‘e−0’ indicates the position after the last character in a string. Tospecify a position that covers the first character in a string,parameters ‘s+0 . . . s+1’ can be used. As an example of a rule withpositional parameters, the rule {ValidStrings=s+0 . . . s+2, “He” }creates a constraint on a corresponding string in which the first twocharacters must be ‘He’.

In an illustrative embodiment, substring parameters can be used forspecifying a substring that has been generated according to a rule thatdivides a string. For example, the {split} rule and the {Substring} rulecan be used to divide a string into substrings. Substrings can benumbered using a zero-based index calculated from the beginning of theoriginal undivided string. Substring parameters can use the syntax s‘x−y’, where x is the first substring and −y is optional and describes arange of substrings. Still further, by using the literal character ‘x’as opposed to a non-negative number, the ‘x’ is replaced by the lastsubstring found in the original string. Alternatively, by using asubstring parameter of “s‘*’”, the rule applies to all substrings. As anexample of how substring parameters can be used, if a user enters thestring “Excel files|*.xls|All Files|*.*” along with the rules{Split=“|”} and {Lock=s‘1’, s‘3’} into the authoring user interface 302,the string will be split on the ‘|’ character. Further, the first andthird substrings—‘|*.xls|’ and ‘|*.*’—generated by the split rule willnot be localized according to the lock instruction.

FIG. 6 is a flow diagram illustrative of a source-data processingroutine 600 which can be implemented by the illustrative operatingenvironment 100 depicted in FIG. 3 in accordance with an aspect of thepresent invention. At block 602, the one or more metadata compilers 104obtains source data. In an illustrative embodiment, the source data isin the form of user input from an authoring user interface 302. Further,the source data can include a source string. Still further, the sourcedata can include attributes, such as an instruction, additional resourceinformation, and/or an inferred restriction. In an illustrativeembodiment, a facade component can direct the source data from theauthoring user interface 302 to the appropriate metadata compiler basedon the characteristics of the source data. At block 604, the source datais compiled into metadata. In an illustrative embodiment, the metadatacan include one or more constraints which correspond to evaluationcriteria and one or more anchor points operable to project theconstraints onto a string.

At block 604, the metadata optimizer and arbitrator 106 normalizes themetadata. FIG. 8 is a flow diagram of a normalization sub-routine 800implemented by the metadata optimizer and arbitrator 106 in accordancewith an aspect of the present invention. At block 802, the metadataoptimizer and arbitrator 106 obtains abstract metadata. In anillustrative embodiment, the abstract metadata can be obtained from oneor more metadata compilers 104. At block 804, the metadata optimizer andarbitrator 106 reduces redundant constraints to a single equivalentconstraint. For example, if one constraint on a target string specifiesa maximum length of twenty elements while another constraint on thetarget string specifies a maximum length of ten, then the metadataoptimizer and arbitrator 106 can reduce the two constraints to a singleequivalent constraint specifying a maximum length of ten. The metadataoptimizer and arbitrator can make this reduction because any stringshorter containing fewer than ten elements will also contain fewer thantwenty elements.

At block 806, the metadata optimizer and arbitrator performs conflictresolution. Conflict resolution can include resolving incompatibilitiesamongst a plurality of constraints. For example, one constraint canspecify a maximum length of ten while another constraint specifies aminimum length of twenty. Clearly, no single string can satisfy both ofthese constraints and thus the constraints are incompatible. Themetadata optimizer and arbitrator 106 can resolve the incompatibility.In an illustrative embodiment, the optimizer 106 can resolve theconflict by simply picking one constraint and discarding the other.Further, the metadata optimizer and arbitrator 106 can provide a warningthat an incompatible constraint is being discarded. Alternatively, auser or administrator can decide which constraint to keep. In anillustrative embodiment, incompatibilities can be resolved based onother attributes associated with a source or target string. Incompatibleand/or redundant constraints can be generated by multiple metadatacompilers 104 or can be generated by a single metadata compiler 104. Inan illustrative embodiment, the metadata optimizer and arbitrator 106makes no assumptions about inputs. For example, the optimizer 106 doesnot assume that metadata from a single compiler is free of incompatibleor redundant constraints. At block 808, the sub-routine 800 returns toroutine 600.

Returning to FIG. 6, at block 608 a projection component 110 projectsmetadata onto a string. The string can be a target string entered by auser at the translation user interface 402. Further, the metadata can benormalized, abstract metadata obtained from the metadata optimizer andarbitrator 106. In an illustrative embodiment, projecting metadata ontoa string involves placing constraints and their associated evaluationcriteria on top of the string according to the corresponding one or moreanchor points. For example, constraints 552, 556, 558, 560, and 562 canbe projected onto string “CALCULAT.EXE” 525 using anchor points 520,518, 516, and 522 as depicted in FIG. 5B.

At block 610, a validation component 108 validates a string against theprojected metadata. In an illustrative embodiment, validating aconstraint involves evaluating the portion of the string to which theconstraint is mapped to determine whether the mapped portion satisfiesthe evaluation criteria that corresponds to the constraint. For example,constraint 556 in FIGURE,5B is evaluated by determining whether theportion of the string between anchor points 520 and 518 has less than 8elements. Because the portion of the string to which the constraint 556is mapped (“CALCULAT”) has less than 8 elements, the constraintevaluates to “true.” In an illustrative embodiment, validation component108 continues processing the other constraints associated with a stringuntil all constraints have been evaluated. Further, in an illustrativeembodiment, a string is valid if all associated constraints evaluate to“true.” A string is not valid if any of the constraints evaluate to“false.” Nevertheless, a string can be valid if some constraints are notsatisfied. For example, if a failed constraint generates a warningmessage as opposed to an error message, then a corresponding string canstill be valid.

At block 612, a validated string along with the metadata used tovalidate the string can be displayed to a user. In an illustrativeembodiment, a string and combined metadata can be displayed on anauthoring user interface 302. Further, the metadata can be used to marka string such that a user can determine which portions of the string arevalid and which portions are not valid. Marking and displaying a stringwill be discussed in more detail below in relations to FIGS. 12-15. Atblock 614, the routine 600 terminates.

FIG. 7 is a flow diagram illustrative of a target-data processingroutine 700 which can be implemented by the illustrative operatingenvironment 100 depicted in FIG. 4 in accordance with an aspect of thepresent invention. At block 702 a projection component 110 obtainstarget data and metadata. In an illustrative embodiment, the projectioncomponent 110 can obtain target data from a translation user interface402. Further, the target data can include a target string. Stillfurther, the target data can include attributes corresponding to thestring. In an illustrative embodiment, the projection component 110 canobtain normalized abstract metadata from the metadata optimizer andarbitrator 106. Alternatively, the projection component 110 can obtainmetadata from a data store.

At block 704, the projection component 110 projects metadata onto thetarget string. Examples of strings with projected metadata are depictedin FIGS. 5B-5D. At block 706, a validation component 108 validates thetarget string. In an illustrative embodiment, the metadata obtained atblock 702 can include constraints operable to validate a particular typeof string, such as a filename, and the target data can include a stringto be validated for conformity with the requirements of the particulartype of string.

With continued reference to FIG. 7, at block 708, a translationcomponent 404 translates the target. Lock constraints can be mapped toone or more portions of a target string and thus restrict the one ormore portion of the string from being translated. For example, aplaceholder restriction can prevent a corresponding placeholder in atarget string from being translated. In an illustrative embodiment, astring can be translated from any source language to any targetlanguage. Further, the translation component 404 can performpseudo-localization of a string. Pseudo-localization will be discussedin more detail below. At block 710, the translated target can becorrected. For example, the translated target string may not satisfy theconstraints included in the projected metadata. A string that does notsatisfy associated constraints can be modified such that the modifiedstring satisfies the constraints. For example, string 524 from FIG. 5Acan be modified by deleting “OR” to conform with the constraints 552,556, 558, 560, and 562 depicted in FIG. 5B. At block 712, thetranslation and associated metadata is displayed to a user. In anillustrative embodiment, the translation can be displayed on translationuser interface 402. Further, the associated metadata can be used to markthe string. Marking of a string will be discussed in more detail below.At block 714, the routine 700 terminates.

FIG. 9 is a block diagram 900 depicting the conversion of data from oneor more resources into a resource-neutral format before beingtranslated. In an illustrative embodiment, string “FOO {0}” can beassociated with Resource A 902. Further, the substring “{0}” from “FOO{0}” can be associated with a placeholder restriction. A placeholderrestriction can prevent an associated placeholder within a string frombeing translated. String “FOO % 1” can be associated with Resource B904. Further, the substring “% 1” from “FOO % 1” can be associated witha placeholder restriction. In an illustrative embodiment, Resource A 902can be associated with one particular platform, whereas Resource B canbe associated with a different platform.

Block 906 depicts the conversion of strings “FOO {0}” and “FOO % 1” intoa resource neutral format. In an illustrative embodiment, the respectiveplaceholders “{0}” and “% 1” can be converted into a resource neutralform (e.g., “<PH\>”). Between blocks 906 and 908, a pseudo-translationof the string can be performed to generate string “fÕÕ<PH\>”, which isdepicted at block 908. The placeholder restriction can prevent theplaceholder (“<PH\>”) from being pseudo-localized. At block 910, thestring “fÕÕ<PH\>” can converted back into the resource-dependent form“fÕÕ{0}” which is dependent upon Resource A. Similarly, at block 912,the string “fÕÕ<PH\>” can be converted back into the resource-dependentform “fÕÕ{0}” which is dependent upon Resource B. By convertingresource-dependent strings into a resource-neutral format beforetranslating or performing other actions on the strings, the translatingor processing code can be made simpler because the code only has toprocess data in a single resource-neutral format. In an illustrativeembodiment, resource neutralization can be used to translate stringsthat differ only on locked portions. Further, placeholders and escapedcharacters are resource-dependent and can be transformed intoresource-neutral forms.

FIG. 10 is a flow diagram illustrative of a fuzzying routine 1000implemented by a translation component 404 in accordance with an aspectof the present invention. At block 1002, the translation component 404obtains metadata that has been projected onto a string. At block 1004,resource-format neutralization can be performed on the string. Asdiscussed above in relation to FIG. 9, resource-format neutralizationcan be used to convert resource-dependent portions of a string into asingle resource-neutral format. At block 1006, random content isgenerated. The random content can be representative of a translatedversion of the string included in the projected metadata.

At block 1008, the metadata obtained at block 1002 is projected onto therandom content. Further, at block 1010, the projected metadata can beused to modify the random content such that the random content satisfiesthe projected constraints. The projected metadata can includeplaceholders and escaped characters which are inserted into the randomcontent such that the random content satisfies the projectedconstraints. At block 1012, any resource-neutral constraints that wereinserted into the random content so that the random content wouldsatisfy the projected constraints are converted into resource-dependentform. The fuzzying routine 1000 can be used to generate random contentwhich satisfies metadata associated with a source string. In thismanner, the fuzzying routine 1000 can create various pseudo-translationsof a string which can be used for testing purposes. At block 1014, theroutine 1000 terminates.

FIG. 11 is a flow diagram illustrative of a regular expressionconversion routine 11000 implemented by a metadata compiler 104 inaccordance with an aspect of the present invention. In an illustrativeembodiment, regular expressions can be converted into metadata includingone or more constraints which correspond to evaluation criteria and oneor more corresponding anchor points. Converting regular expressions intometadata can simplify the metadata normalization and translationprocesses. At block 1102, the one or more metadata compilers 104 obtainsa regular expression and a source string from an authoring userinterface 302. For example, a metadata compiler 104 can obtain a sourcestring such as “This is aa file” and a regular expression rule such as{Regex=“a {2}”} from the authoring user interface 302. Regularexpressions are well-known in the art and the one or more metadatacompilers 104 are operable to process any regular expression. At block1104, the one or more metadata compilers 104 can parse the regularexpression such that metadata including one or more constraints and oneor more corresponding anchor points can be derived from the regularexpression.

With continued reference to FIG. 11, at block 1106, the metadataexpression is matched against the source string. At block 1108, theconstraints can be projected onto the source string Using the exampleregular expression {Regex=“a{2}”} and the example source string of “Thisis aa file”, a lock constraint can be placed on the first occurrence oftwo consecutive ‘a’ characters in the source. Thus, a lock constraintcan be placed on ‘aa’ in the source string “This is aa file”. In anotherexample, the one or more metadata compilers 104 can obtain the exemplaryregular expression {Regex=“a[abc]{3}”} to be matched against theexemplary source string “This is abbc file.” The exemplary regularexpression can be parsed to create a lock constraint on the firstoccurrence of an ‘a’ followed by three letters that are either ‘a’, ‘b’,or ‘c’, in addition to a valid characters constraint on the followingthree characters which must be either ‘a’, ‘b’, or ‘c’. Additionally, amaximum length constraint with length 3 and a minimum Length constraintwith length 3 would cover the same section. Matching the derivedconstraints to the exemplary source string “This is abbc file” wouldcreate a lock constraint on ‘a’ and the valid characters constraint,maximum length constraint, and minimum length constraint on the ‘bbc’portion of the source string. In an exemplary embodiment, because thesource string satisfies all constraints, the source string is valid. Atblock 1110, the routine 1100 terminates.

Referring back to FIG. 5D, in an illustrative embodiment, the split rulecan be used with a regular expression parameter to generate some of thedepicted constraints. For example, if a user wants to generateconstraints such that only text sections of string 572 will betranslated, a user can split the string using a regular expression. Anexemplary split rule such as {Split=r“: [0-9:]*:?”} can be used toperform the split. The ‘r’ parameter in the rule can indicate that whatfollows is a regular expression. Further, the one or more metadatacompilers 104 converts the regular expression into lock constraints 576and 588. Still further, the split rule generates substrings “FLY FROMBOTTOM”, “FLY”, and “FROM BOTTOM”.

As discussed above, the substrings generated by a split rule can be usedas parameters in other instructions. Thus, in addition to the split ruleabove, in an illustrative embodiment, a user can enter other rules usingthe substrings generated from the split rule as parameters. For example,to generate constraints 574, 578, and 584, a user can enter a rule ofthe form: {InvalidChars=s‘0-2’, “: ”}. The ‘s’ parameter can indicatethat the instruction will generate constraints for the substrings 0, 1,and 2, which were generated by the split rule above. Thus, combining thesplit rule discussed above with an invalid characters rule, a user canrestrict the substrings “FLY FROM BOTTOM”, “FLY”, and “FROM BOTTOM” fromcontaining the sequence “:” as indicated by constraints 574, 578, and584. Further, a user can use the substrings generated from the splitrule as parameters in a rule to restrict maximum length. For example, arule of the form: {MaxLen=s‘0’, 255} can be used to generate constraint596. Likewise, an exemplary rule such as {MaxLen=s‘1’, 10} can generateconstraint 590 while an exemplary rule such as {MaxLen=s‘2’, 35} cangenerate constraint 586.

FIGS. 6-11 illustrate various methods that may be performed according tovarious aspects of the present invention. However, it will beappreciated that the present invention can perform more or fewer methodsthan depicted by the illustrative figures. Further, the methodsillustrated within each individual figure may include more or fewerelements than depicted in the illustrative figures.

With reference now to FIG. 12, an illustrative user interface 1200 fordisplaying a string 1214 along with associated comments 1202, suggestedvalues 1228 and 1236, and a translation 1244 will be described. In anillustrative embodiment, a comment display portion 1206 can be operableto obtain and display comments associated with the string 1214. Commentscan correspond to attributes. Comments can also correspond to rules thatthe one or more metadata compilers 104 can compile into constraints. Forexample, a user may enter a rule of the form {MaxLen=17} 1204 into thecomment display portion 1206 to indicate that a maximum-lengthconstraint operates on the entire string and limits valid strings tocontaining no more than 17 elements. Placeholders, escaped characters,valid and invalid characters, substring, split, and other types ofconstraints can be placed on a string 1214 by entering the correspondingrule into the comment display portion 1206 of the display 1200.Alternatively, a metadata compiler 104 can infer constraints byanalyzing string 1214. In an illustrative embodiment, comments can alsoinclude resource information. Additionally, syntax errors in the commentdisplay portion 1206 can be marked. Still further, rules can be markedif the corresponding string fails to validate against the rule. Forexample, the number “17” is underlined in rule {MaxLen=17} 1204 becausethe corresponding string 1214 contains more than 17 characters.

An input string display portion 1280 can be used to obtain and display astring 1214. In an illustrative embodiment, the value of the string 1212is displayed as “The saving of file % 1!s! is % 2!d!% complete” 1214.Additionally, the string 1214 can be marked to alert the user of anyconstraints on the string 1214. For example, the word “file” 1216 isitalicized to indicate that file is subject to a term constraint.Further, “% 1!s!” 1218 is underlined to indicate a placeholder. Asdiscussed above, a placeholder prevents the corresponding portion of thestring from being translated. Likewise, “% 2!d!” is also underlined toindicate a placeholder. As will be discussed in more detail below,placeholders 1218 and 1220 in the input string display portion 1280 maynot be translated in the translation display portion 1286.

A percent sign (“%”) 1224 can be marked with an arrow 1222 to indicatean escaped character constraint. However, any type of marking can beused to mark any of the constraints associated with the string 1214. Forexample, highlighting, color-coding, underlining, bold, italics, specialcharacters, shading, arrows, or any other techniques can be used to markthe string 1214. Additionally, a string can be edited at aresource-neutral level. For example, string 1214 could be converted to aresource-neutral format and displayed to a user for editing. Further, astring can be displayed and edited in a format that corresponds to anyresource. For example, a string corresponding to an exemplary resource Acould be converted into a resource-neutral format and thenresource-injected such that the string is displayed and editable in aformat corresponding to an exemplary resource B.

Suggested value 1226 display portions 1282 and 1284 can be used todisplay suggested modifications 1228 and 1236 for input string 1214. Forexample, display portion 1282 may suggest that the percent sign (“%”)1224 be escaped 1234 because a certain resource interprets the percentsign 1224 as a special character. By escaping the percent sign 1234, theresource will not give the percent sign its special meaning. Similarly,display portion 1284 may suggest that the percent sign 1224 be replacedwith the word “percent” 1238. A user may select one or more of thesuggested values 1228 and 1236 for translation. The suggested values1228 and 1236 can have more or fewer placeholders than the input string1214. Additionally, metadata in the suggested values 1228 and 1236 canbe visually indicated using various marking techniques. Suggested values1228 and 1236 can be generated by a translation memory, by machinetranslation, or through other translation techniques. Further,suggestions can appear on the display 1200 as auto-completes as the usertypes.

In an illustrative embodiment, the input string display portion 1280 andsuggested value display portions 1282 and 1284 can be associated withgraphics that indicate confidence levels 1208 and translationavailability 1210. For example, input string 1214 can be associated witha graphic 1290 that indicates how difficult it would be to machinetranslate. Further, a graphic 1254 can indicate the number of languagesto which a string can be translated. For example, graphic 1254 canindicate that a translation memory has 0 associated translations for theparticular input string 1214. Each suggested value display portion 1282and 1284 can also be associated with a graphic 1292 and 1294 thatindicates how difficult the respective, associated suggested values 1228and 1236 would be to machine translate. Graphic 1292 visually indicatesthat suggested value “Savingfile % 1!s!. % 2!d!%% complete.” 1228 isavailable in 2 languages 1252, whereas graphic 1294 visually indicatesthat suggested value “Savingfile % 1!s!. %2!d! percent complete.” 1236is available in 15 languages 1250. The illustrative user interface 1200can also include a graphic 1248 that visually indicates which suggestedvalue is available in the most languages. Additionally, translationavailability graphics 1210 and/or confidence level graphics 1208 cancorrespond to a specific market or markets.

In an illustrative embodiment, a translation 1244 of the source string1214 or a suggested value 1228 or 1236 can be provided in a translationdisplay portion 1286. In an illustrative embodiment, the translation canbe a sample (pseudo) translation 1242, which can be produced using thefuzzying technique described above in relation to FIG. 10, for example.Additionally, a translation can be into any language. Typically,placeholders 1220 and 1218 will not be translated. Further, placeholderscan be associated with functional portions of the string. In anillustrative embodiment, translation 1244 can be the result of afuzzying technique that first generated random content and thencorrected the random content according to metadata including one or moreconstraints and one or more corresponding anchor points. For example,placeholders 1220 and 1218 could have been placed in the random contentto satisfy the constraints associated with the metadata of thecorresponding source string 1214.

Spell-checking can be incorporated into the display 1200 and suggestcorrections to misspelled words. Further, terms can be described as amouse pointer hovers over the terms. Still further, differences betweensuggested values 1228 and 1236 and the input string 1214 can be markedto provide the user with a quick visual indication of the differences.Additionally, an indication of how input strings can be used can beprovided. Further, terms can be marked to indicate that they areapproved by certain organizations or groups. The display 1200 can beconfigurable such that the user can turn features on and off. Markingscan be used to indicate any terms that have been replaced in the sourcestring 1214. If a certain portion of a string is associated with a lowconfidence level, that portion can be indicated with markings.Additionally, functional problems in a translation 1244 can be markedand suggestions to correct functional problems can be displayed.

With reference now to FIGS. 13-15, an illustrative user interface 1300for translating a source string 1504 in a source language into a targetstring 1516 in a target language will be described. As depicted on theoverlaid diagram, on a high level, an item with projected metadata 1520can be entered into an input string display portion 1502, the metadatacan be projected onto a target string and validated 1522, and the targetstring 1516 can be displayed as an item with projected metadata 1524 ona translation display portion 1512. FIGS. 13-15 depict an exemplaryiterative process a user can utilize to generate a target string 1516that satisfies the metadata associated with a corresponding sourcestring 1504.

With reference now to FIG. 13, tables representative of projectedmetadata 1526 and 1550 can be associated with the source string 1504 andtarget string 1516, respectively. Column 1536 of table 1526 can indicatethe type of metadata, column 1538 can indicate which data from thestring is associated with the metadata, and column 1540 can indicate theposition of the metadata in relation to the string. Each constraint inthe source string 1504 can be represented by a row in the displayedprojected metadata table 1526. For example, row 1528 can indicate that aterm constraint with an associated identification of “7” can be foundbetween positions 8 and 12 on the source string 1504. The termconstraint can correspond with the term “file” 1506. Term constraints ina source string can map to an equivalent term in a target string.Continuing with the example, row 1530 can indicate that an indexedplaceholder represented by “{0}” 1508 can be found between positions 13and 16 on the source string 1504. Similarly, row 1532 can indicate thatan indexed placeholder represented by “{1}” 1510 can be found betweenpositions 18 and 21 on the source string 1504. Row 1534 can indicatethat a ‘{’ character and a ‘}’ character are subject to escapedcharacter constraints and may be found anywhere within the source string1504. Additionally, row 1534 can indicate that special character “{” canbe escaped by the sequence “{{” while special character “}” can beescaped by the sequence “}}”. Because the special characters “{” and “}”in the source string 1504 are not escaped, source string 1504 does notcontain any escaped characters, except on the placeholders within thestring. In addition to displaying the position of constraints on astring, the type or types of anchoring associated with a constraint canbe displayed. For example, placeholders “{0}” 1508 and “{1}” 1510 can beloose anchored to the beginning and end of string 1504. An indicationthat placeholders 1508 and 1510 are loosely anchored to the beginningand end of the string can be displayed. Conversely, the escapedcharacters 1534 would be hard-anchored to the beginning and end ofstring 1504. An indication that the escaped characters constraint 1534is hard-anchored to the beginning and end of the string can bedisplayed.

Still with reference to FIG. 13, various markings can be used asindicators in accordance with the metadata 1526 associated with thesource string 1504. For example, bold font can be used in the sourcestring 1504 to indicate that the term “file” 1506 is subject to a termconstraint. Likewise, bold font can be used to mark the first indexedplaceholder “{0}” 1508 and the second indexed placeholder “{1}” 1510.However, any type of marking can be used to visually alert a user to themetadata associated with a string. For example, italicized and othertypes of fonts, larger or smaller fonts, color-coding, extraneouscharacters on the display, highlighting, underlining, and shading canall be used to visually set off portions of a string that are associatedwith metadata.

A table of attributes 1512 and 1514 can be associated with the source1504 and target 1516 strings respectively. The attribute tables 1512 and1514 can indicate the associated resource or platform in addition to theusage of the string. For example, a string can be used in a dialog box.Further, the attribute tables 1512 and 1514 can indicate anidentification of the platform and the language of the associatedstring. As discussed above, resource neutralization can be used totranslate a string from a language on one platform into a differentlanguage on another platform. By using resource neutralization, aneutralized string can be translated once and then the resource-neutralportions of the string can be converted into resource-dependent portionssuch that the single translation can be used on several differentresources. Thus, only one resource-neutral string is translated asopposed to several resource-dependent strings.

Table 1542 can be used to display abstract metadata pulled from theprojected metadata displayed in table 1526. Abstract metadata can beplaced against a string for validation. Because abstract metadata is notassociated with a string, table 1542 may not include a position column1540. Table 1544 can display information related to the translation. Forexample, a terminology provider and associated identification can bedisplayed. Column 1546 can display the source and target language of acorresponding term 1506. Additionally, column 1548 can display thesource and target values of a corresponding term 1506. Suggestedtranslations for other terms in the source string 1504 can also bedisplayed. Accordingly, table 1544 can assist the user in translatingterms correctly.

As depicted in FIG. 13, a user can begin the process of translatingsource string 1504 by typing “Die Dat” 1516 into the target stringdisplay portion 1512. “Dat” 1552 can be marked in bold because it can berecognized as the beginning of the translation for “file” 1506 asdisplayed in table 1544. Additionally, table 1550 can be utilized by auser to determine which constraints are satisfied and which are notsatisfied. For example, table 1550 displays the metadata gathered fromthe source string and its corresponding position 1540 on the targetstring 1516. Because the phrase “Die Dat” 1516 does not fulfill therequirements of the constraints shown in table 1550, the position column1540 displays a “Not Found” message for each corresponding constraint.Further, table 1550 can display warning and error messages 1554, 1556,and 1558. For example, row 1554 can display a warning message indicatingthat the required term “Datei” has not been completely entered. Further,rows 1556 and 1558 can display error messages indicating thatplaceholders “{0}” 1508 and “{1}” 1510 are missing. Using these warningand error messages, a user can begin to correct the translation 1516.Alternatively, suggested corrections can be displayed as auto-completesfor selection by the user.

As depicted in FIG. 14, a user can continue to enter a translation 1516of the source string 1504. For example, a user can enter a translation1518 of the required term “file” 1506. The translated term 1518 can beidentified between positions 4 and 9 on the target string displayportion 1512 as depicted in row 1576. Further, indexed placeholder “{0}”1508 can be identified between positions 10 and 13 on the target stringdisplay portion 1512 as depicted in row 1578. Still further, thebeginning of indexed placeholder “{1}” 1570 can be identified. In anillustrative embodiment, because indexed placeholder “{1}” 1510 is notentered correctly, the placeholder is labeled as “Not Found” in row1580. Alternatively, because character “{” in item 1570 is unescaped anda required placeholder is missing, an error can be displayed as depictedin row 1574 indicating that item 1570 is invalid.

Still with reference to FIG. 14, various markings can be used asindicators in accordance with the metadata 1550 associated with thetarget string 1516. For example, bold font can be used to indicate thatthe term “Datei” 1518 is required in the target string 1504. Likewise,bold font can be used to mark the first indexed placeholder “{0}” 1508.Further, items that could correspond to a constraint when completelyentered, such as item 1570, can also be marked in bold font. Any type ofmarking can be used to visually alert a user of the metadata associatedwith a string. For example, italicized and other types of fonts, largeror smaller fonts, color-coding, extraneous characters on the display,highlighting, underlining, and shading can all be used to visually setoff portions of a string that are associated with metadata.

To assist in generating a valid target string 1516, error messages 1572and 1574 can alert a user to portions of the string which do not satisfythe associated metadata. For example, row 1572 can indicate to the userthat placeholder.“{1}” 1510 is missing from the target string 1516.Still further, row 1574 can notify the user of an unescaped escapecharacter. Because escape characters have special meaning, they caneither be escaped or correspond to a constraint. A user can utilize themetadata 1550 and error messages 1572 and 1574 to generate a validtarget string 1516.

FIG. 15 depicts an illustrative embodiment in which a valid targetstring 1516 has been entered into the target string display portion1512. As described above, items 1518, 1508, and 1510 of the targetstring 1516 can correspond to constraints and can be marked in bold.Further, the position of each corresponding item can be depicted incolumn 1540. For example, column 1540 indicates that required term“Datei” 1518 can be found between positions 4 and 9 on the target stringdisplay portion 1512. Likewise, indexed placeholder “{0}” 1508 can befound between positions 10 and 13 while indexed placeholder “{1}” can befound between positions 28 and 31. Additionally, the lack of error andwarning messages in table 1550 can indicate that a valid target string1516 has been entered in the target string display portion 1512.Further, if any escaped characters are identified, the position of theescaped characters can be provided in column 1540 at row 1582.
